no red hair guy on the cover but a red haired guy does work at a gym
OMG YES, THANKS SM
No, that's on me though. the guy in the cover had black hair not red hair
happy to help^^
So, like, the main cover has a red-haired guy lying down and (maybe, I'm not sure) hands on him. The red-haired guy works at a gym. Uhm, so that's all I remember. It is a full-color manhwa, though.
